Upgrade Cards and Spans

Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

This chapter explains how to upgrade common control cards, DS3-12 and DS3N-12 cards, and optical spans for the Cisco ONS 15454.

Before You Begin

This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs)..

Caution Always upgrade the standby cross-connect card. Removing an active cross-connect card can cause a protection switch unless a lockout is in place. If the standby card is being upgraded, a lockout is unnecessary.

Step 3 Determine the standby XCVT card. The ACT/STBY LED of the standby XCVT card is amber, while the ACT/STBY LED of the active XCVT card is green.

Step 4 Physically replace the standby XCVT card on the ONS 15454 with an XC10G card:

a. Open the XCVT card ejectors.

b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the upgrade is complete.

c. Open the ejectors on the XC10G card.

d. Slide the XC10G card into the slot along the guide rails.

e. Close the ejectors.

Note On the XC10G card the fail LED above the ACT/STBY LED becomes red, blinks for several seconds, and turns off. The ACT/STBY LED turns amber and remains on. In node view, the XC10G appears as the standby XCVT.

Step 5 In node view, click the Maintenance > Cross-Connect tabs.

Step 6 From the Cross Connect Cards menu, choose Switch.

Step 7 Click Yes on the Confirm Switch dialog box. Traffic switches to the XC10G card you inserted in Step 4. The ACT/STBY LED on this card changes from amber to green.

Step 8 Physically remove the now standby XCVT card from the ONS 15454 and insert the second XC10G card into the empty XCVT card slot:

a. Open the XCVT card ejectors.

b. Slide the XCVT card out of the slot.

c. Open the ejectors on the XC10G card.

d. Slide the XC10G card into the slot along the guide rails.

e. Close the ejectors.

The upgrade is complete when the second XC10G card boots up and becomes the standby XC10G card. In node view, both the active and standby cards will change to XC10G.

Stop. You have completed this procedure.

NTP-A296 Upgrade the TCC2 Card to the TCC2P Card

Purpose

This procedure upgrades the TCC2 card to the TCC2P card. The TCC2 and TCC2P cards support ONS 15454 Software R4.0 and later software versions.

Tools/Equipment

Two SONET TCC2P cards

Two TCC2 cards

Prerequisite Procedures

None

Required/As Needed

As needed

Onsite/Remote

Onsite

Security Level

Maintenance or higher

Note The TCC2P card does not support software earlier than R4.0. You will not be able to revert to a software release earlier than Software R4.0 with TCC2P cards installed.

Step 4 Before you begin the upgrade, complete the "NTP-A108 Back Up the Database" procedure on page 15-4. Make sure ONS 15454 Software R4.0 or later is installed on the node. Refer to the release-specific software upgrade document. TCC2 and TCC2P cards are not compatible with releases prior to Software R4.0.

Step 5 Physically replace the standby TCC2 card on the ONS 15454 with a TCC2P card.

a. Check the LED on the faceplate. The ACT/STBY LED on the faceplate of the TCC2 card indicates whether the card is in active or standby mode. A green ACT/STBY LED indicates an active card and an amber light indicates a standby card.

b. Open the standby TCC2 card ejectors.

c. Slide the card out of the slot. This raises the IMPROPRMVL alarm which will clear when the upgrade is complete.

Note During a TCC2 upgrade, the CONTBUS-IO-A or CONTBUS-IO-B TCC A (or B) To Shelf Slot Communication Failure alarm is raised as the TCC2 briefly loses communication with the backplane. This alarm usually clears after approximately 13 minutes. If the condition does not clear after a period, log onto http://www.cisco.com/tac for more information or call TAC (800) 553-2447.

Note It takes approximately 10minutes for the active TCC2 card to transfer the database to the newly-installed TCC2P card. During this operation, the LEDs on the TCC2P flash Fail and then the active/standby LED flashes. When the transfer completes, the TCC2P card reboots and goes into standby mode after approximately three minutes. Do not remove the card from the shelf during a database transfer.

Caution If your active TCC2 card resets during the upgrade before the new TCC2P card has come to a full standby mode, remove the new TCC2P card immediately.

Step 6 When the newly installed TCC2P card is in standby, go to the active TCC2and right-click the card.

Step 7 From the drop-down list, click Reset Card.

Wait for the TCC2 card to reboot. The ONS 15454 switches the standby TCC2P card to active mode. The TCC2 card verifies that it has the same database as the TCC2P card and then switches to standby.

Step 8 Verify that the remaining TCC2 card is now in standby mode (the ACT/STBY LED changes to amber).

The ONS 15454 boots up the second TCC2P card. The second TCC2P card must also copy the database, which can take approximately10 minutes. Do not remove the card from the shelf during a database transfer.

Step 10 If power-related alarms occur after the second TCC2P card is installed, check the voltage on the backplane. See the "DLP-A33 Measure Voltage" task on page 17-39 for instructions. Refer to the Cisco ONS 15454 Troubleshooting Guide for information on clearing alarms.

Stop. You have completed this procedure.

NTP-A93 Upgrade the DS3-12 Card to the DS3-12E Card

Purpose

This procedure upgrades the DS3-12 card to the DS3-12E card or the DS3N-12 card to the DS3N-12E card. This procedure can also be used to enable the capabilities of a DS3-12E card that was installed in a shelf with Software R3.1 or earlier.

Note Upgrades must be performed between two N-type cards or two non-N-type cards. You cannot upgrade between an N-type card and a non-N-type card. When physically replacing a card, the new card must be in the same slot as the old card. The DS3-12E card upgrade supports 1:1 and 1:N protection schemes. The procedure is non-service affecting for protected cards; that is, the upgrade will cause a switch less than 50 ms in duration.

Caution Protect cards must be upgraded before working cards because working cards cannot have more capabilities than their protect card.

Note During the upgrade some minor alarms and conditions appear and then clear on their own; however, there should be no Service-Affecting (SA, Major, or Critical) alarms if you are upgrading protected cards. (Upgrading an unprotected card can be service affecting.) If any service-affecting alarms occur, Cisco recommends backing out of the procedure. See the "A254 Downgrade a DS3-12E/DS3NE Card to a DS3-12/DS3N-12 Card" procedure.

Step 3 Determine if the card you are upgrading is protected or unprotected:

a. A protected card will be listed under Protection Groups in the Maintenance > Protection tabs. The slot, port, and status (that is, Protect/Standby, Working/Active) of each card will be listed in the Selected Group.

b. An unprotected card will not be listed in the Protection Groups/Selected Group in the Maintenance > Protection tabs.

Caution Traffic will be lost during an upgrade on an unprotected card.

Step 4 If the card you are upgrading is unprotected, skip this step and go to Step 5 and ignore references to the protect card and protect slot. If the card you are upgrading is protected, make sure the protect card is not active. If the card status is Protect/Active, perform a switch so that the working card becomes active:

Caution Protect cards must be upgraded before working cards because working cards cannot have more capabilities than their protect card.

Caution After upgrading a DS3XM-6 card to a DS3XM-12 card, the newly installed DS3XM-12 card will run in STS-12 mode. To change the backplane throughput rate, make sure the card is out-of-service and not carrying live traffic. Changing the backplane throughput rate on a in-service cardcan cause a traffic outage of up to 30 seconds.

Note During the upgrade some minor alarms and conditions appear and then clear on their own; however, there should be no Service-Affecting (SA, Major, or Critical) alarms if you are upgrading protected cards. (Upgrading an unprotected card can be service affecting.) If any service-affecting alarms occur, Cisco recommends backing out of the procedure.

Note You cannot have any DS-1 cards installed on the same side of the shelf as the DS3/EC1-48 card when you finish the low-density to high-density upgrade.

Step 3 Determine which low-density card(s) (DS-1, DS-3, DS-3E) you want to upgrade to high-density, according to slot limitations.

Note For 1:N protection groups, the protect card is installed in Slot 3 on the A side of the shelf and Slot 15 on the B side. For 1:1 protect groups, working and protect cards can be installed in any traffic slot.

The following limitations apply if you are upgrading a low-density protect card:

•The protect card must be in a protection group.

•The protect card must not protect any low-density electrical cards in Slots 4, 5, or 6 on the A side of the shelf (Slots 12, 13, or 14 on the B side).

•For 1:N protection groups where N = 2: On the A side, the protect card cannot be upgraded if any electrical cards are installed or preprovisioned in Slots 4, 5, or 6 (or Slots 12, 13, or 14 on the B side).

•For 1:N protection groups where N = 1: On the A side, if the protect card is installed in Slot 3 and it protects a low-density card in Slot 1, the protect card cannot be upgraded if Slot 5 or 6 has an electrical card installed or preprovisioned. For the B side, if the protect card is installed in Slot 15 and it protects a low-density card in Slot 17, the protect card cannot be upgraded if Slot 12 or 13 has an electrical card installed or preprovisioned.

•For 1:N protection groups where N = 1: On the A side, if the protect card is installed in Slot 3 and it protects a low-density card in Slot 2, the protect card cannot be upgraded if an electrical card is installed or preprovisioned in Slot 4. On the B side, if the protect card is installed in Slot 15 and it protects a low-density card in Slot 16, the protect card cannot be upgraded if an electrical card is installed or preprovisioned in Slot 14.

•The DS3XM-12 card can protect a DS3XM-6 or DS3XM-12 card on the other side of the shelf, but the protected card must be in portless mode.

The following limitations apply to upgrading a working card after you have upgraded the protect card:

•A working card in Slot 1 on the A side (Slot 17 on the B side) cannot be upgraded if an electrical card is installed or preprovisioned in Slot 5 or 6 (Slot 12 or 13 on the B side).

•A working card in Slot 2 on the A side (Slot 16 on the B side) cannot be upgraded if an electrical card is installed or preprovisioned in Slot 4 (Slot 14 on the B side).

b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the upgrade is complete.

Step 12 Change the low-density card to the high-density card in CTC:

a. Right-click the slot where you removed the low-density card and choose Change Card from the drop-down list.

b. Choose the new card type from the Change to drop-down list.

c. Click OK.

Step 13 Insert the new high-density electrical card into the slot where you removed the low-density card. Be sure to remove the plastic protective covers on rear of the card before installing the card:

a. In node view, double-click the slot where you installed the high-density card in Step 13.

b. In the Maintenance > Protection tab, double-click the protection group that contains the reporting card.

c. Click the selected group.

d. Click Clear and click Yes in the confirmation dialog box.

The protect card in should now become standby.

Note If you have upgraded to a DS3XM-12 or DS3/EC1-48 card and are using 734A cables with UBIC electrical interface adapters (EIAs), you must set the line build out (LBO) parameter for Ports 13 to 48, doing so according to the actual distance (in feet) from the DSX panel. If you incorrectly set the LBO for these cards and ports, the terminal loopback might not work on Ports 14 and 17 on cards installed in Slots 1 or 17.

If you are using 735A cables, you must set the LBO parameter for Ports 13 to 48, doing so according to the following conventions:

Actual distance from the DSX panel is less than 110 feet (33.53 m): LBO setting is " 0 - 225."If you incorrectly set the LBO for these cards and ports, the terminal loopback might not work on Ports 14 and 17 on cards installed in Slots 1 or 17 with unterminated cable pairs.

Actual distance from the DSX panel is greater than or equal to 110 feet (33.53 m): LBO setting is "226 to 450." However, the terminal loopback might not work on Ports 14 and 17 on cards installed in Slots 1 or 17 when used in this configuration with unterminated cable pairs. If the terminal loopback does not function, create a physical loopback at the DSX panel.

Step 15 Repeat Steps 4 through 14 for any other low-density cards you want to upgrade to high-density cards.

Stop. You have completed this procedure.

NTP-A254 Downgrade a DS3-12E/DS3NE Card to a DS3-12/DS3N-12 Card

Purpose

This task downgrades a DS3-12E or DS3NE card. Downgrading can be performed to back out of an upgrade.The procedure for downgrading is the same as upgrading except you choose DS3-12or DS3N-12 from the Change Card drop-down list.

Step 3 Determine if the card you are downgrading is protected or unprotected:

a. A protected card will be listed in the Protection Groups area on the Maintenance > Protection tabs. The slot, port, and status (that is, Protect/Standby, Working/Active) of each card will be listed under Selected Group.

b. An unprotected card will not be listed under Protection Groups/Selected Group in the Maintenance > Protection tabs.

Caution Traffic will be lost during an upgrade on an unprotected card.

Step 4 If the card you are upgrading is unprotected, skip this step and go to Step 5 and ignore references to the protect card and protect slot. If the card you are upgrading is protected, make sure the protect card is not active. If the card status is Protect/Active, perform a switch so that the working card becomes active:

a. Double-click the protection group.

b. Click the Protect/Active card.

c. Click Switch and Yes in the Confirmation dialog box.

Step 5 Physically remove the working DS3-12E card or the working DS3N-12E card:

a. Open the DS3-12E or DS3N-12E card ejectors.

b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the downgrade is complete.

Step 6 Right-click the slot to be downgraded and choose Change Card from the drop-down list.

Step 7 Choose DS3-12 or DS3N-12 from the Change to: drop-down list.

Step 8 Click OK.

Step 9 Insert the DS3-12 or DS3N-12 card into the working slot:

a. Open the ejectors on the DS3-12 or DS3N-12 card.

b. Slide the DS3-12 or DS3N-12 card into the slot along the guide rails.

Step 10 Close the ejectors. Wait for the IMPROPRMVL alarm to clear and the card to become active.

The span upgrade procedure requires at least two technicians (one at each end of the span) who can communicate with each other during the upgrade.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Caution Do not perform any other maintenance operations, such as facility or terminal loopbacks, or add any circuits during a card or span upgrade.

Note OC-N transmit and receive levels should be in their acceptable range as shown in the specifications for each card in Table 2-3.

Note During the upgrade, the IMPROPRMVL alarm may be raised. It will clear automatically.

Note A four-port OC-3 to eight-port OC-3 upgrade, or an OC-12 to four-port OC-12 upgrade can only be performed from multispeed slots (Slots 1 to 4 and 14 to 17) because the OC3-8 and OC12-4 card can only be installed in multispeed slots. Ensure that the OC-3 and OC-12 cards are in multispeed slots before performing a span upgrade to the OC3-8 and OC12-4. The four OC-3 ports will be mapped to Ports 1 to 4 on the eight-port OC-3 card. The OC-12 port will be mapped to Port 1 on the four-port OC-12 card.

Note BLSR protection channel access (PCA) circuits, if present, will remain in their existing STSs. Therefore, they will be located on the working path of the upgraded span and will have full BLSR protection. To route PCA circuits on protection channels in the upgraded span, delete and recreate the circuits after the span upgrade. For example, if you upgrade an OC-48 span to an OC-192, PCA circuits on the protection STSs (STSs 25 to 48) in the OC-48 BLSR will remain in their existing STSs (STSs 25 to 48) which are working, protected STSs in the OC-192 BLSR. Deleting and recreating the OC-48 PCA circuits moves the circuits to STSs 96 to 192 in the OC-192 BLSR. To delete circuits, see the "A278 Modify and Delete Overhead Circuits" procedure. To create circuits, see "Create Circuits and VT Tunnels."

Step 1 Determine the type of upgrade you need to make and be sure you have the necessary cards.Valid card upgrades include:

•Four-port OC-3 to eight-port OC-3

•Single-port OC-12 to four-port OC-12

Valid span upgrades include:

•Single-port OC-12 to OC-48

•Single-port OC-12 to OC-192

•OC-48 to OC-192

Caution You cannot upgrade a four-port OC-12 span. If the ring contains any OC12-4 cards and you need to upgrade all the spans in the ring, you will need to downgrade the OC12-4 card to a single-port OC-12 card (which is only possible if one port on the OC12-4 card is being used).

Note The Span Upgrade option will only be visible and available if the hardware necessary for the upgrade is present; for example, no upgrade is possible from an OC-48 span unless XC10G cards are installed in the nodes at both ends of the span.

Note During the upgrade/downgrade some minor alarms and conditions display and then clear automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than BLSROSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any other service-affecting alarms occur, Cisco recommends backing out of the procedure. A four-node BLSR can take up to five minutes to clear all of the BLSROSYNC alarms. Allow extra time for a large BLSR to clear all of the BLSROSYNC alarms.

Step 4 In network view, right-click the span you want to upgrade.

Step 5 Choose Span Upgrade from the drop-down list.

Step 6 The first Span Upgrade dialog box appears (Figure 12-1). Follow the instructions on the dialog box and the wizard will lead you through the rest of the span upgrade.

Note The Back button is only enabled on Step 2 of the wizard; because you cannot back out of an upgrade via the wizard, close the wizard and initiate the manual procedure if you need to back out of the upgrade at any point beyond Step 2.

Figure 12-1 Span Upgrade Wizard

Caution As indicated by the wizard, when installing cards you must wait for the cards to boot up and become active before proceeding to the next step.

Note Remember to attach the fiber after installing the OC-N cards.

Note The span upgrade process resets the line's CV-L threshold to factory default. The CV-L threshold is reset because the threshold is dependent on line rate.

NTP-A95 Upgrade OC-N Spans Manually

Purpose

This procedure upgrades OC-N speeds within BLSRs, path protection configurations, and 1+1 protection groups by upgrading OC-N cards. Complete a manual upgrade task if you need to perform error recovery for the Span Upgrade Wizard or back out of a span upgrade (downgrade).

Note OC-N card transmit and receive levels should be in their acceptable range as shown in the specifications section for each card in Table 2-3.

Note In this context the word "span" represents the OC-N path between two nodes. The words "span endpoint" represent the nodes on each end of a span.

Note If any of the cross-connect cards reboot during the span upgrade, you must reset each one when the span upgrade procedure is complete for all the nodes in the ring.

Step 1 Determine the type of span you need to upgrade and make sure you have the necessary cards. Valid span upgrades include:

•Four-port OC-3 to eight-port OC-3

•Single-port OC-12 to four-port OC-12

•Single-port OC-12 to OC-48

•Single-port OC-12 to OC-192

•OC-48 to OC-192

Caution You cannot upgrade a four-port OC-12 span. If the ring contains any OC-12-4 cards and you need to upgrade all the spans in the ring, you will need to downgrade the OC-12-4 card to a single-port OC-12 card (which is not possible unless only one port on the OC12-4 card is being used).

Note During the upgrade/downgrade some minor alarms and conditions display and then clear automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than BLSROSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any other service-affecting alarms occur, Cisco recommends backing out of the procedure. A four-node BLSR can take up to five minutes to clear all of the BLSROSYNC alarms. Allow extra time for a large BLSR to clear all of the BLSROSYNC alarms. Refer to the Cisco ONS 15454 Troubleshooting Guide for information about alarms.

Note The span upgrade process resets the line's CV-L threshold to factory default. The CV-L threshold is reset because the threshold is dependent on line rate.

Note The Span Upgrade option will only be visible and available if the hardware necessary for the upgrade is present; for example, no upgrade is possible from an OC48 span unless XC10G cards are installed in the nodes at both ends of the span.

Note A four-port OC-3 to eight-port OC-3 span upgrade, or an OC-12 to four-port OC-12 span upgrade can only be performed from multispeed slots (Slots 1 to 4 and 14 to17) because the OC3-8 and OC12-4 card can only be installed in multispeed slots. Ensure that the OC-3 and OC-12 cards are in multispeed slots before performing a span upgrade to the OC3-8 and OC12-4. The four OC-3 ports will be mapped to Ports 1-4 on the eight-port OC-3 card. The OC-12 port will be mapped to Port 1 on the four-port OC-12 card.
